Transforming the UXO risk management industry.
S.I UXO is the fruition of decades of renowned UXO engineering knowledge and experience underpinned by an ambition to transform the industry.
S.I UXO is an established UK UXO risk management contractor founded by former military EOD specialists and geotechnical engineers, with leadership bringing 50+ years of combined field experience and an ambition to “transform the industry”.
The business delivers end-to-end UXO risk mitigation for land and marine developments, working from early planning through to on-site delivery and post-clearance outputs, aligned to CIRIA C681 and industry best practice.
S.I UXO provides a full-spectrum UXO risk management service aligned with CIRIA C681 and UK planning best practice, supporting construction, infrastructure, marine, and energy projects from feasibility through to intrusive works and final sign-off.
At the pre-construction and planning stage, S.I UXO delivers Preliminary and Detailed UXO Risk Assessments founded on rigorous historical research, including detailed wartime bombing analysis, military land-use records, aerial photographic interpretation, and site-specific geotechnical correlation. Assessments are evidence-led, defensible, and proportionate, enabling clients, designers, and regulators to make informed decisions on risk, scope, and cost control.
A key differentiator is S.I UXO’s tracked CPT-based intrusive detection capability, allowing high-confidence interrogation of UXO risk in challenging ground conditions, reducing duplication, programme risk, and overall cost.
